These Greg Egan short stories (Axiomatic) are good - short enough to fit my limited attention span. By my estimates they average just over 400 calories long. (This becomes less confusing when you understand that I like to read during a brisk walk on a treadmill.) Each story explores a potential future scenario and highlights the effects on real people in a believable, concise plot. In each one I usually catch a couple of glimpses of his dry wit hiding in the drama.
